APPARATUS FORV'THE MANUFACTURE or SOLID BAND-TIRES. 7

of Lancaster, England, have invented certain new and useful Improvements in Apparatus for the Manufacture of Solid Band- Tires, of which the. following is a specification.

-This invention relates to apparatus for the manufacture of solid band tires, and is f placed beneath the interior. roller C (or applicable to the manufacture by either of the methods of building up the tiresknown as calendering or as forcing;

This invention consists in mountingthe interior roller or rollers upon stationary oradjustable supports or bearings and the. exterior supporting rollers in bearin s carr ed by a cross head of hydraulic ram by which the desired pressure can be applied to the rubber as it is applied to or wrapped around the band. I

The invention will be fully described with reference to the accompanying drawings:

Figure 1 is a side elevation.

Fig. 2 is a front elevation.

Fig. 3 is a plan of guide for directing the rubber on to the band.

Fig. 4 is an end elevation of same.

Fig. 5 is a longitudinal section.

The foundation band A'to which the rubber is applied rests upon and is supported by the exterior rollers B B and is held in position by an interior roller 0. while pressure is being applied.

Two or more rollers may take the place of the single roller C. e

The interior rollerC. (or rollers) may be mounted to rotate on a fixed stud or support 0 carried by the frame G or may be journaled in fixed bearings in a suitable frame and against the interior roller or rollers any desired amount of pressure may be applied. Or the support or bearings for the roller or rollers C may be adjustable by screw or otherwise if desired.

A single roller is at present preferred set mid-way between the exterior rollers B B.

The bearings for the journals of the exterior rollers B B are carried by the cross head D of a hydraulic ram 03 which can be moved to and from the interior roller or rollers C to applypressure to the band A when in position thereon.

A guide E with guide flanges e is mounted over the roller B and in front of the band Specification of Letters Patent.

A, to shape the rubber and prevent it spreading asit is built up or molded intoa tire. The flanges e serve as knives or scrapers to cut off any surplus rubber from the side of the band A, and the guide E is shaped to impart the desired contour to the tire as it is built up. The guide E may rest upon a table F and is moved to and fro by a screw 7 or other device. I

The foundation band A for the tire is rollers) and rests upon the two rollers B B carried by the ram 03 and the latter is raised until the interior of 'the ban d is pressed against the roller C. Thejunction rubber is first applied preferably in strip form be tween the rollers and the periphery of the foundation band A, the pressure forcing the rubber. into the-grooves and serrations of the band as the latter. revolves. The tread rubber is then applied in a similar manner I to protect by Letters Patent is 1. In apparatus for the manufactureof solid tires from a foundation band, a frame,
